Speeincation of Letters Patent.

Application led November 4, 1,913. Serial No. 799,091.

To all whom, t may concern:

Be it known that we, VVILLTAM J. WAIN- wm'cn'r and ll'nnMAN R. SMrrir, citizens of the United States, residing at Brainerd, county of (Took, and State. of Illinois, and New York, county and State of New York, respectively, have invented certain new and useful Improvements in Machines for Manufacturing Spil-ally Reinforced Iile- Shells, of which the following is a full, clear, and exact description.

In the -n'lamlfactme of piles of concrete it is customary to-form a thin shell of metal of the shape and size of the pile, to drive the same by means of a core, to withdraw' the core after the pile has been driven and to fill the shell with concrete. As the shell serves merely as a receptacle for the soft concrete and in time is destroyed by the action of air and water, it becomes desirable to make it as stron as possible by the use of the least quantity of material, and for this purpose it has been proposed to make the shell ofv thin sheet metal reinforcedby wire wound spirally and contained in a groove of corresponding form in the material of the shell. The invention subject of this application for Letters Patent is a machine for applying to or incorporating with the shell such wires. 1

v There are numerous features of im rovement embodiedin the machine the mam feature of which is the use of two devices movable longitudinally with respect to a mandrel over Which the shell may be forced and one of whiehwinds a wire spirally around the mandrel and the other forces the interior of the shell around lthe wire.

The other features of invention are in details of construction which may bebest described-and understood by reference to the accompanying drawings. l

Figure 1 is a view partly in elevation and artly in section of the complete machine. Fig. 2 is an elevation of the reinforcedportion of the shell. Fig. is a side view in eleii'a-tion and part section of the machine. Fig. 4 is a top plan view of the same. F ig.

Fig. '6 is a similar sectional view on line r-L of Fig. 1. Fig. 7 is a vertical sectional view of the mandrel. Fig. Sis a section of the same on line .11 -ai of Fig. 7. Fig. 9 is a section on the line y/-g/ of the same figure. Fig. 10 1s an enlarged detailA of the wire winding mechanism. Fig. 11 is a vertical sect-ion, and 12 a sectional elevation of the lneans for compressing the material of the shell around the wire. i

Similar letters of reference in the several figures indicate corresponding parts of the device. i

r1`he apparatus comprises a collapsible mandrel or eorc for carrying the shell which 'part is indicated by the letter A. This element rests upon an anti-friction bearing upon a. suitable base and is provided with a shaft Il by means of which it is rotated by a continuously driven power shaft C adapted to be thrown into and out of gear by a clutch D. The construction of the mandrel will be understood by reference to Figs. 7,

8 and 9 in which it is shown as composed of three parts A, A2, A3, which in operation are forced outwardly by a rod E with beveled ends which is screwed or otherwise forced down over inclined surfaces when the shell is in place. To adapt the mandrel to shells of varying size the lower ends of the segments are provided with dowel .pins e which enter eccentric slots in a base plate F turned by a gear and pinion G that may be turned, as by a wrench, the blocks 7), are

brought together to bind or clamp the end of a wire.

On either side of the mandrel and having a. pivotal connection with the base isa suitable support I( or I1 having, in the main. the form ofia half tube. Through these supports extend two threaded rods K and Ii which are adapted toV be rotated in either direction by the main power shaft subst-autially in the manner shown in Figs. 1. 5 and (l. That is to say, on the main spindle I is loo lili

a gear wheel M and arms N 'turning abput said shaft and carrying gear wheels O vmeshing with pinions P. The pinions P are on l short spindles mounted in the base and carry beveled gears P that mesh with bevel gears P2 on. a horizontal shaft having a featheredI connection with spindles Q movable longi-V tudinally by means of screw .threaded sleeves R so as to bring either of two bevel gears on the shafts Q into mesh withbevel gears on the ends of' screw rods K", L or to release the rods from engagement with the gearing.

. The special purpose of this arrangement 1s to permit the supports K and L to be moved with reference to the mandrel to which they must always bear a fixed relation when in operation. j It will be seen that the upper ends of the supports K and are attached to the head H by bolts working in slots` and that the supports for said devices are movable to and from the axes of the core or mandrel.

On one of thescrew rods, as, L', is the wire winding device and on the other K" is the device for forcing the shell around the n which is moved in guide-ways bya threaded spindle operated'by a pinion p in gear with a pinion having a bevel wheel "s which is turned by a bevel wheel t, the shaft of which is ladapted to receive a handle.

The grooving device' is a wheel with sunken periphery of a width slightlyless than the distance between wires and the method or effect of its operation is clearly` illustrated in Fig. l1.

` The operation of the machine will be readily understood from the above description to be as follows The grooving attachment having been withdrawn from the mandrel the end of a wire is inserted in the upper clamp Z2 and the machine started in operation with the -winding attachment in proximity to the mandrel. The gearing and pitch of the screw on the rods K and L are so arranged that for one revolution of the mandrel thel carriage of the winding'device or that for the grooving device travels vertically about three inches and a groove of this pitch is cut in the mandrel so that by the operation of the device the wire is wound therein. When the winding carriage has covered the mandrel the wire is secured by the lower clamp b and cut off, and the winding device withdrawn from the mandrel. A sheetmetal shell is then forced down over the wire-wound mandrel, the grooving attachment brought into operation therewith/ and i the machine again started. The wheel U by this operation is forced into` the shell of metal and carries the same around the wire, grooving the shell as shown in Fig. 2, and as the grooving device descends the winding device ascends, so that when the operation is completed, the machine is in condition` for the application of another wire. The grooving device is always at its lowest point at` and any suitable devices may be employed for this purpose Again, when the. shell is forced down over the wire around the mandrel the wire is not sufficiently tight against the shell. Moreover, by the operation of the grooving attachment the diameter of the shell is slightly increased, but as it is necessary that the wire should be in firm contact with the shell, in practice it is necessary to screw the shell,-after the grooving operation, down over the wire, and this may be done by means of a roped sling or any other 1devices suitable for the purpose,

After the operation is complete, the mandrel is collapsed in Athe usual manner and the shell with 'the wire incorporated therewith is removed. During the operation, it will be understood, that the supports K and L must be exactly parallel with the mandrel -and not onlv the particular means shown and described but any other suitable for the purpose may be employed for' effectin'g such parallelism.

,Having now described the invention in the best manner known to us in which it may be practised, we claim:
